Specification of Lettera Patent.

Patented Oct. 27, 1908.

Application led February 15, 1907. Serial No. 357,498.

To all whom it may concern:

j Be it known that I, WILLIAM E. LATIMER, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Extension Foot- Rests; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

The object of my present invention is to provide an extension and adjustable foot rest for chairs which is compact in construction easily and conveniently operated, not liable to stick or get out of order and an unobjectionable attachment for a chair and strong and eiicient.

Figure l shows a perspective view of a chair with my foot rest attachment applied and shown in extended position. Fig. 2 is a partial cross section of the frame with the foot rest attachment applied and shown in one of its exten-ded positions. Fig. 3 is a detail showing particularly a cross section of the track or rail and the manner of securing it to the chair seat frame. Fig. 4 is a similar view to Fig. 2 with the foot rest attachment folded or closed and occupying its closed position under the seat frame. Fig. 5 is an enlarged detail of one of the main members of the attachment, which may be termed the sliding extension arm. Fig. 6 is an end view of the same in connection with a cross section of the rail or track. Fig. 7 is a plan y view of the sliding extension arm member shown in Fig. 5. Fig. 8 is a side elevation of the other main member which may be termed the swinging extension arm. Fig. 9 is a plan view of the same. Fig. 10 shows a Vdetail of a removable pivot.

Referring to the reference letters and ligures in a more particular description, 1 and 2 indicate the front and rear rails of a chair seat frame, to the under side of which the inverted T-shaped rail 3 is secured by hangers or brackets, 5, 5. In the construction as shown bands or webbings 6 support the spiral spring 7 of the seat, although these details are not particularly important. Mounted on the rail or track 3 is the primary sliding extension arm 8, the slide or way portion of which is indicated at 8"i and is arranged at the rear end of the arm, and is arranged in a plane somewhat above that of the main body of the arm, the arrangement being such that the body of the arm can be projected forward from under the seat and parts supporting the rail or track hanger 5. The arm 8 consists in the main of two side walls between which is received the secondary swinging extension arm 9. The side walls are joined at the top as more particularly shown in Fig. 6 and have slotted openings Sb therein, which slotted openings are given an upward turn at their forward end. The forward end of the arm 8 is provided with an opening 8c through which passes the body of the swinging extension arm 9, and at the forward lower corner the arm is provided with a shoulder 8d. At the shank end the arm 9 is provided with a series of ratchet teeth 91L arranged in a curve adjacent to the pivot. The pivot is a removable piece of the form shown in Fig. l0 having reduced ends and is indicated by 10. The reduced ends of the pivot l0 fit in the slots 8b, while the body portion fits in an opening in the shank of the arm 9. The swinging end of the arm 9 is forked as shown at 9b in order to furnish a wider base therefor and receives the stool 11 pivoted thereon, so as to swing from a position on the top of the arm as shown more particularly in Figs. l and 2 to a position under the arm as shown more particularly in Fig. 4.

In assembling the parts the shank end of the arm 9 may be inserted through the opening 8c and `passed through to a position where the shank end will extend beyond the rear end of the part 8. The pivot piece 10 will then be placed in position and the arm forced forward, the ends of the pivot enter* ing the rear ends of the slots 8b. Vhen thus assembled the parts are secured together by a rivet or pin 11, which serves as a stop for the rearward movement of the arm 9 with reference to the extension arm 8. Ou the underside of the arm 9 adjacent to the forward end there is provided a catch shoulder 9c adapted to engage with the shoulder 8 on the part 8.

The operation of the device may be briefly described as follows: When the foot rest is in folded position, as shown in F ig. t, the operator takes hold of the stool l1 and draws the two parts 8 and 9 out from under the chair seat as far as the part S is adapted to move along the rail or track 3. The part S can be Y caused to move by reason of the catch 9c engaging with the shoulder 8d. Vhen the part 8 has assumed its normal forward position, by slightly elevating the swinging end of the arm 9 theV same may be drawn forward to its full extended position more or less as desired. The stool l1 will then be turned over on to the top of the arm and the arm 9 may be given more or less of an elevation from the plane of the arm 8 by engaging one or the other of the ratchet teeth on the shank end with the shoulder 8d of the arm 8. The stool may be brought closer to the chair seat even when in an elevated position, by sliding the extension arm 8 backwardly on the rail or track 3. Vhen any weight is placed on the stool ll the arrangement is such that the slide will bind on the rail or track to suiiicient extent to prevent it moving too readily.

It will be noted that the construction is such as to give suflicient strength to the device and still the arms 8 and 9 each being single and mounted on a single track under the seat of the chair, there is little or no obstruction to or inconvenience given to the occupant of the chair in getting in or out thereof. In closing the foot rest attachment the swinging extension arm 9 will first be folded within the extension arm S, and the stool l1 turned over into its inverted position when the whole may be readily slid under the seat of the chair in which it occupies a compact and unobjectionable position. The central web of the rail 3 projects above the plane of movement of the slide Sa and prevents the webbing or bands, which support the seat springs from interfering with the free sliding movement of the extension arm and other members of the foot rest attachment.

1What I claim as new and desire to secure by Letters Patent is:

The combination in a foot rest attachment for chairs of a single rail secured to the under side of the chair seat and extending from front to rear centrally thereof, a primary extension arm provided with a slide portion at its rear mounted to slide on said rail and support the' arm rigidly therefrom whereby the arm is adapted to be projected beyond the front of the seat or withdrawn thereunder and supported at all times by the rail and slide, a secondary extension arm mounted on and folding within the primary port the secondary arm in extended position of angular adjustment, and a stool mounted on the outer end of the secondary arm, substantially as set forth.
